The General Services Administration (GSA) Green Proving Ground released three new sets of its evaluations results. The agency tests promising sustainable building technologies in real-world settings in federal facilities. The highlights from three these tests include:
High performance (High-R) window retrofits use advanced materials to deliver up to a seven-fold improvement in the thermal performance of windows. At a GSA test bed location in Provo Utah, installation of a High-R retrofit kit reduced heating loads by up to 41 percent.
Variable speed chillers equipped with magnetic levitation (maglev) bearing compressors represent an important innovation in commercial air conditioning. By eliminating the metal-on-metal friction of traditional compressors, maglev technology improves energy efficiency while minimizing any negative impacts of noise and vibration.
The Photovoltaic (PV) Guidance report explores conditions and practices associated with successful PV projects in GSA’s portfolio. In this report, the Green Proving Ground assessed the execution and management of 63 GSA-owned PV projects to identify a broad set of best practices for on-site PV deployment.
GSA is deploying those technologies that research shows to be ready for immediate use.
